Abstract

This paper examines the physical, optical, and electrical characteristics of cesium tin-germanium triiodide based single halide Perovskite absorption materials in order to provide the best photovoltaic application. In light of the diversification of the use of natural resources, perovskite solar cells are becoming more and more essential for capturing renewable energy. In this research work, a cesium tin–germanium triiodide (CsSnGeI3) perovskite-based solar cell (PSC) has been reported to achieve a high-power-conversion efficiency (PCE).  CsSnGeI3 perovskite-based solar cell has been proposed for the Pb and toxic-free (Al/FTO/ TiO2/CsSnGeI3/Mo) structure simulated in Solar Cell Capacitance Simulator (SCAPS-1D software. At first aluminum, fluorine-doped tin oxide, Titanium dioxide, cesium tin–germanium triiodide and   Molybdenum have been inserted into SCAPS and simulated using specific temperature. In this simulation, the electron transport layer (ETL) FTO, the buffer layer  TiO2, and the absorber layer  CsSnGeI3 were all used. Utilizing variations in thickness including absorber and buffer, defect density, operating temperature, back contact work function, series and shunt resistances, acceptor density, and donor density, the performance of the proposed photovoltaic devices was quantitatively assessed. Throughout the simulation, the absorber layer thickness was held constant at 1.6 ?m, the buffer layer at 0.05 ?m, and the electron transport layer at 0.5 ?m. A solar cell efficiency of 24.75%, an open-circuit voltage of 0.95 volts, a short-circuit current density of 30.61 mA/cm2, and a fill factor (FF) of 85.42% have all been recorded for the  CsSnGeI3 absorber layer. Our ground-breaking findings unequivocally show that CsSnGeI3-based PSC is a strong contender to quickly overtake other single-junction solar cell technologies as the most effective.

Abstract

In order to provide the best photovoltaic application, this paper examines the physical, optical, and electrical aspects of Cesium Titanium (IV) based single halide Perovskite absorption materials. Perovskite solar cell for scavenging renewable energy, has grown more and more necessary in the context of the diversification of the use of natural resources. Due to its efficient band gap of 1.8 eV, Cs2TiI6 has become a desirable contender for today's thin-film solar cell. This article shows the spectrum responses of a planar Au/FTO/C60/Cs2TiI6/CH3NH3SnI3/Al based structure where CH3NH3SnI3 is used as a Hole transport layer (HTL) and C60 and FTO are utilized as Electron transport layers (ETL) under 300K temperature conditions. This research demonstrates that employing Fluorine doped Tin Oxide (FTO) and Ultrathin Fullerene (C60) as Electron transport layer charge extraction can be achieved. FTO provides high transmission, strong conductivity, and good adherence for the deposited layers. When used in a coevaporated perovskite solar cell, a C60 layer with an ideal thickness less than 15 nm improves charge extraction. This article tried to avoid cadmium for solar cell generation due to its toxicity on environment. The simulation included detailed configuration optimization for the thickness of the absorber layer, HTL, ETL, defect density, Wavelength, temperature, and series resistance.  In this work the Power Conversion Efficiency (?), Fill Factor (FF), Open-circuit Voltage (Voc), J-V Curve, Quantum Efficiency and Short-circuit current (Jsc) have been measured by varying thickness of absorber layer in the range of 1µm to 6 µm. Energy harvesting effectiveness, cost-effectiveness of perovskite solar cells is all impacted by their PCE, which is a crucial characteristic. The key variables that define a perovskite solar cell's performance are the Voc and fill factor (FF). When the voltage is zero, the solar cell can produce its maximum current, which is represented by the (Isc).  The optimized perovskite solar cell shows a power conversion efficiency of 21.8429% when the absorber layer thickness is 4µm and electron transport layer thickness is 0.6µm.
